    摘要: A VCSEL (113) having a first and a second stack of distributed Bragg reflectors (120, 116) and an active region (118) defining a light generating and emitting path. A layer (104) of semiconductor material is formed on the second stack (116) so as to intersect the light path and a first electrode (106) and a second electrode (108) are disposed on the layer (104) to form a metal-semiconductor-metal photodetector (102). The metal-semiconductor-metal photodetector (102) absorbs some of the light emitted by the VCSEL (113) and provides an indication of the light output intensity, which indication may be used to control the VCSEL (113).

    摘要: Fiber optic transmitter and receiver electrical elements are implemented on separate vertical boards in fiber optic modules. An optical block implements lenses and reflecting surfaces to minimize manufacturing costs. The light receiver and light transmitter are mounted to receive and transmit non-orthogonal to the fiber axis to avoid optical cross talk. In one embodiment, receiver and transmitter are mounted at an angle greater than forty-five degrees with a perpendicular line to the reflective surfaces. In another embodiment, receiver and transmitter are mounted at an angle less than forty-five degrees with a perpendicular line to the reflective surfaces. The reflective surface for transmission may be a beam shaper to improve light beam uniformity and optical coupling and to avoid active alignment. The vertical boards have ground planes facing each other to minimize electrical cross talk. An optional shielded housing provides further shielding for reducing EMI.

    摘要: A fiber-optic module having a housing/shielding unit and a module chassis frame having optical, electrical and electro-optical components. The housing/shielding unit functions both as a protective outer housing and an electromagnetic shield. The housing/shielding unit includes forward fingers for a flush mounting in one embodiment and backward fingers for an extended mounting in another embodiment. The fingers can contact a bezel, faceplate or wall of host system to ground the housing/shielding unit to a chassis ground. The module chassis frame may be formed of a conductive material and grounded as well through a host system faceplate or otherwise to the chassis ground. A transmit ground for transmitter components and a receive ground for receiver components are isolated from the chassis ground.

    摘要: The invention is a method and apparatus for transmitting the light from one or more transmitting arrays of optical devices to one or more receiving arrays of optical devices where each optical device in a transmitting array transmits an initially diverging light beam to a single optical device in a receiving array. Each optical device in a receiving array receives a converging light beam from a single optical device in a transmitting array. The method consists of imaging the optical devices in one or more transmitting arrays on the optical devices in one or more receiving arrays. The light rays from each optical device in a transmitting array are superimposed on the light rays from the other optical devices in the transmitting array while traversing a common volume.
